Pixie Lott's fiance Oliver Cheshire among people who pinned minicab driver down after Natural History Museum incident

Pixie Lott’s fiance has told how he pinned down a taxi driver who injured 11 people after mounting a pavement outside London’s Natural History Museum.

Model Oliver Cheshire, 29, was among people who reportedly pinned the man down after the incident on Saturday afternoon.

The driver sparked a major terror alert after the black Toyota Prius mounted the pavement in the heart of London’s museums district, but Scotland Yard later confirmed it was “not being treated as a terror-related incident”.

A man in his 40s was arrested on suspicion of dangerous driving and taken to a North London police station.

Describing the moment he and several others pinned down the “screaming” minicab driver after he hit his Jaguar, Mr Cheshire told the MailOnline: “I got out and grabbed him – three of us grabbed him – and someone phoned the police.

“He was an Uber driver, according to the girls that were in his car. I have never seen anything like it.”

Mr Cheshire later tweeted: “Thanks for messaging everybody. I’m ok. Thank you to the men who helped me pin him down and the police for coming so quickly.”

According to the London Ambulance Service, those injured in the incident suffered mainly head or leg injuries and most have now been discharged.

A Metropolitan Police spokesman described the incident as a “road traffic investigation and not a terrorist-related incident.”

Pictures and video footage from the scene in Exhibition Road showed street damage and a massive police presence in the popular tourist area.

Some images showed the black Toyota Prius, registered with Transport for London (TfL) as a minicab, that had collided with a silver Vauxhall saloon and a Jaguar.

Sophie Parry and Lesley Guinness were on their way to the V&A’s Pink Floyd exhibition when they saw the driver of a black vehicle swerve across the road and hit a cyclist.

Ms Parry, 56, said: “I thought maybe someone might have had a heart attack behind the wheel.

“Because I thought, this is strange for a vehicle – it must have been going pretty slow there to career across and do all that damage.

“It’s odd, because any vehicle there was maybe going three, four, five, six miles an hour. So I thought maybe someone had had a heart attack or something.”

Dieon Rurora, 25, who works in a nearby cafe, said: “People were running down the street, falling over. It was quite scary.”

Colleague Merilin Mueller, 20, added: “It just seemed like an accident because there was a police car. We couldn’t see outside.

“Then there were loads of police cars and that’s when all of these police came marching down saying, ‘move, move’. They said, ‘you need to evacuate’.”
